The SiT92315 is a HCSL-LP, 20 output differential fanout clock buffer that meets or exceeds all the performance requirements of the Intel DB2000QL specification. This buffer is ideal for PCI-Express Gen 1 to Gen 6 or QP/UPI applications and comes in a compact LGA package with a standard pin configuration.
The SiT92315 offers three modes to control all the 20 outputs. They can be controlled either through the SMBus interface, the side band interface, or output enable pins.
